Air Flotation Series 

Dissolved Air Flotation (DAF): Generates micro-fine bubbles that adhere to suspended matter, dropping their density below water to skim them via buoyancy. Excellent for low-temperature, low-turbidity, or algae-heavy waters.

Vortex Concave Air Flotation: Uses a vortex aeration machine to inject micro-bubbles directly without pre-dissolving air or requiring pressure vessels/air compressors. It features a negative pressure zone return system, reducing operational power demands.

Vertical Flow Air Flotation: Integrates intake, flocculation, separation, and skimming inside a compact cylindrical steel structure, optimizing bubble attachment time (20–80 µm bubbles).

High-Efficiency Shallow Air Flotation: Formulated around "shallow pool theory" (600–700 mm depth) and the "zero-speed principle" (water relative velocity to pool wall is near zero). Ensures static-state particle rising, reaching suspended solids removal rates above 90%.

Multi-Plate Screw Press Dewatering Machines 

Technology: A continuous filtration device using a screw shaft traversing a series of fixed and moving rings. Sludge moves from a gravity thickening section to a high-pressure dewatering zone. The concentric ring movement provides continuous self-cleaning, removing the risk of clogging and eliminating the need for standalone thickening tanks. 

Plate and Frame Filter Press 

Technology: Composed of alternating solid filter plates (with drainage grooves) and hollow frames compressing filter cloth media. Operates under fully enclosed conditions using manual or hydraulic mechanical pressure locking, resulting in a dewatered sludge cake with significantly higher solid content compared to alternative systems. 

Quartz Sand Filters  

Technology: Employs multi-grade compacted quartz sand beds to purify water using a combined membrane filtration, osmosis filtration, and contact coagulation mechanism. 

Activated Carbon Filters   

Technology: Non-powered physical and chemical carbon bed adsorption units.

Key Benefits: Highly effective at eliminating foul odors, color, residual chlorine, and dissolved heavy metal ions (such as hexavalent chromium and mercury).

Green Johkasou  

The Green Johkasou, developed in Japan, this compact, buried tanks use advanced biological processes to purify domestic sewage before safely releasing it into the environment. It is a high-efficiency, decentralized wastewater purification system designed for single households or small businesses with a discharge rate of up to 800 LPD. Engineered for longevity, the unit is constructed from high-strength, injection-molded PP/PE with a robust wall thickness of 7 mm or more, ensuring an underground service life of no less than 30 years. Its compact physical footprint (1230 x 813 x 897 mm) allows for easy, low-impact installation.

To drive its advanced purification, the system comes complete with an outdoor-rated electrical control cabinet and a 50 W, 220 V aerator pump delivering an 80 L/min airflow—fully compatible with standard grid, solar, or wind power setups. This hardware powers an AO (Anoxic/Oxic) Contact Oxidation Process. As domestic wastewater flows into the system, continuous oxygenation feeds localized aerobic microbes on specialized hydrophilic sponge and volcanic rock bio-media, rapidly neutralizing odors and breaking down pollutants. The result is a highly reliable system that takes raw influent (300 mg/L or less COD / 120 mg/L or less SS) and discharges clean, compliant effluent (100 mg/L or less COD / 60 mg/L or less SS) that meets strict regional rural discharge standards (DB34/3527-2019).
